Enver Gjokaj did make an appearance in the movie as someone other than Sousa, and he recently revealed that his Agents of S.H.I.E.L.D. role was originally meant to tie back into his dual role as a cop in The Avengers.
All that said, it’s unclear how Agents of S.H.I.E.L.D. will tie up Sousa’s storyline.
However, it would be wild if Sousa and the team landed in 2012, circa The Avengers’ timeline.
The series’ showrunners have teased a potential MCU connection being on the way, and time travel would certainly explain how both of Gjokaj’s roles could exist in the same universe.
